The density of cast aluminum alloy is lower than that of cast iron and cast steel

Second, the density of cast aluminum alloy is lower than that of cast iron and cast steel, but its specific strength is higher. First of all, cast aluminum alloy has some advantages that other castings caot match. Because the melting point is low, casting methods such as metal molds and pressure casting can be widely used to improve the cootation quality, dimensional accuracy, appearance smoothness and production power of castings.

Especially since the lightweight of automobiles, cast aluminum alloy castings have been widely used in the car industry. Because of the large latent heat of condensation of aluminum alloy, under the same weight, the condensation process of molten aluminum is China Aluminum alloy parts of engine Foundry much longer than that of cast steel and cast iron at all times. Therefore, selecting aluminum alloy castings under the same load conditions can reduce the weight of the layout. Third, aluminum alloy has outstanding casting function.ufeff

Aluminum castings are widely used in life, and everyone has a good evaluation of aluminum castings. It has excellent liquidity and is beneficial to casting thin-walled and disorderly layout castings. Therefore, aluminum alloy castings are widely used in the aviation industry, power machinery and transportation machinery
